液壓輪式裝載機(jī)傳動(dòng)系統(tǒng)性能研究
[Abstract]:Hydraulic drive loader has great advantages over traditional drive loader in many aspects, such as automatic control, system structure, power and so on. Hydraulic loaders have been well applied abroad, but the domestic research has only been paid attention to in recent years. In this paper, the load characteristics of the walking system and the working characteristics of the engine are analyzed, the matching scheme between the engine and the external load is put forward, and two working modes of the loader are put forward. Then this paper puts forward the control scheme of constant power control of pump, high pressure automatic variable control of motor and variable power control of pump in working condition, and adopts the hydraulic control strategy of rotating speed in the starting stage, and puts forward the control strategy to deal with engine overload. Then, this paper carries on the matching and checking of the parameters of the driving system of hydraulic loader, and gives the principle of parameter matching. Combined with the parameter and control theory, the transmission efficiency of the hydraulic drive loader in the working stage is estimated, which proves that the control strategy in this paper is also reasonable in the system economy. Finally, the hydraulic simulation software combined with the parameter matching results is used to simulate the control strategy of the system, which proves the feasibility of the control strategy proposed in this paper. It has certain reference significance for the research of hydrostatic driven vehicle.
